HINGE.

Specification of Letters Patent.

i'satented June 19, 1906.

Application filed. June 24,1905. Serial No. 266,830.

Be it known that I, J osnrn O. ANDERSON,

' a citizen of the United States of America, residing at Cordova, in the county of Walker and State of Alabama, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to improvements in and particularly to hinges for screenone object of the invention being to hinge composed of members adaptthe door being adapted to detachablyengage the member on the door-frame, whereby the door may be applied for use and removed without the necessity of detaching .any screws or otherfastenings and by the aid of unskilled labor without marring the doorframe.

Another object of the invention is to provide improved means for holding the members assembled and permitting of their ready, detachment and also to provide spring means for positively holding the door in either full open or closed position.

Another object is to provide a hinge of this i. character which is simple, durable, reliable, and efficient and adapted to be inexpensively manufactured.

The preferred embodiment of the inventi on is illustrated in the accompanying drawings,

Fgure 1 is a front elevation of the complete hinge. Fig. 2 is a rear elevation of the same. Fig. 3 is a central section on the line 3 3 of Fig. 1. Fig. 4.is a bottom plan view. Fig. 5 is a perspective view of the keeper member of the hinge, and Fig. 6 1s a detail cross-section on line 6 6 of Fig. 2.

The hinge comprises three main parts or members 1, 2, and 3. The part 1 consists of a keeper-plate provided at its outer edge passage of screws to permanentlysecure the same to the hingingjamb of a door-frame. The outer face of this plate is reduced or cut away from a point adjacent to the openings 4 to its inner edge to form a seat for the reception of the member 2, so that the outer face of the latter will lie flush with the outer edge of the keeper-plate. The inner edge of the keeper-plate is curved or rounded, as shown at 5, to permit the part 3 of the hinge to swing without interference, and in its reduced face said keeper-plate is provided with a longitudinal dovetailed slot I or recess 6, flaring or diminishing in width toward its lower end. The inner edge of the keeper-plate is also formedwith openings 4 for the passage of screws" to supplement the action of the screws entered. through the holes 4 to secure said. plate firmly and securely to the door-frame. On the inner edge of the keeperplate, adjacent to the lower end thereof, is a retaining-lug 7, the function of which will be hereinafter described.

attaching-leaf for connecting the hinge proper to the door-frame. This leaf is-adapted to snugly seat againstthe recessed portion of theface of the keeper-plate 1 and is formed tailed locking key or rib 8, adapted to engage the dovetailed slot 6, the construction being such that the leaf 2 is adapted to be applied and removed by a longitudinal sliding movement of the same on the keeper-plate. The locking-rib is inserted and removed through the upper end of the slot 6, and the said rib 8 when applied holds the hinge member firmly connected with the keeper-plate.

The member 3 constitutes an attachingleaf adapted to be fastened to the edge of the door and is provided with openings 9 for the passage of screws for that purpose. leaf is properly shaped at its inner edge to accommodate a substantially semicircular of the member 2 and open on its inner side and at its upper end. The casing is provided at its lower end with abottom wall 11, formed with an open bearing slot or recess 12 to receive a pintle-pin 13, carried by an ear 14,'projecting'from'the lower edge of the member 3. At its upper end the member 2 is provided with a.bearing ear or boss 15, overhanging the open upper end of the easing 10 and having a bearing slot or recess 16 to receive a pi ntle-pin 17, projecting upwardly from an ear 18, carried by the mem ber 3 and projecting between said boss and shield or casing, the member 3 thus being pivotally mounted to swing on the two pintie-pins 13 and 17 and to be detached by ad justing one of the members relativelyto the other to move said pins out of said bearingrecesses.

In order to hold the members 2 and 3 connected, I provide a spring-plate 19, arranged within the shield or casing and detachably secured therein by a removable transverse The member 2 of the hinge constitutes an 'on its inner face with a wedge-shaped dove- This shield or casing 10, formed on the outer edge pin 20. The lower end of this spring-plate bears against a seat 21, formed upon the wall 11 and against the inner end of the pintle 13, thus maintaining a desired frictional pressure on said pintle-pin. The upper end of the spring-plate is bent inward slightly to form a bearing portion which engages a detent-pin 22 depending from the ear 18 into the upper end of the knucklecasing, said spring and detent-pin thus serving to hold the members 2 and 3 connected. By removing the pin 21 the spring-plate may be detached and the members 2 and 3 disconnected in an obvious manner. The detent-pin 22 is of angular form in cross-section and provides oppositelydisposed flat faces 23 and a bearing edge 24. When the door is fully opened or closed, or, in other words, when the leaf 3 is disposed in alinement with or swung outwardly beyond a right-angular relation to the plate 2, the upper end of the spring bears against one or the other of the flat faces 23 and simply main tains the desired amount of pressure thereon to prevent the door from being jarred out of position. The bearing edge 24 is so disposed as to directly engage the spring when the leaf 3 is at right angles to the leaf 2, in which position the spring will therefore exert a binding action to hold the door so disposed. When the door swings slightly outward beyond this position or is only partly opened, however, a full bearing action between the spring and bearing edge of the detent-pin will not be ob tained and said edge will act in the nature of a cam in connection with the spring to thrust the door to a fully open or fully closed position. Provision is thus made for preventing the door from standing slightly ajar and positively closing it, except when it is desired to have it held fully open.

It will be understood part 1 is intended to be permanently fastened to the door-frame and the part 3 to the door, so that when it is desired to hang or detach the door it is simply necessary to adjust the door to bring the dovetailed locking-rib into and out of engagement with the keeper-socket 6, thus obviating the necessity of employing skilled help and removing the hinges and marring the door-frame.

in practice that the In order to prevent casual disconnection of the hinge proper from the keeper-plate when the door is hung, I provide the member 3 with retaining means to cooperate with the retaining-lug 7. To this end 1 construct the car 14 so that it will serve also as a lug to engage under the lug 7, thus preventing the door from being accidentally lifted oil its hinges. The lug 14 is substantially circular in form and is tion 25, adapted to permit the same to clear the lug 7 when the hinge member 3 is fully swung to its open position, whereby the hinge proper may be conveniently attached to and detached from the keeper-plate 1.

Having thus described the invention, what is claimed as new is A hinge of the character described comprising a keeper-plate provided with a recessed face forming a seat portion, said seat portion having a longitudinal dovetailed slot, a hinge proper comprising )ivotally-con nected leaves, one of said leaves having a dovetailed lug to engage the slot in the keeper-plate, the pivotal connections of the leaves comprising detachable engaging portions, a spring associated therewith to hold the same in pivotal engagement, one of the pivotal portions of one of the leaves carrying a detent-pin of angular form in crosssection to provide oppositely-disposed flat faces and a bearing edge to engage and cooperate with the spring, the lug-carrying leaf being shaped to engage the seat of the keeper-plate so that its outer face will lie flush with the unreeessed portion of said plate, and a projection upon the other leaf cooper ating with the retaining-lug on the keeperplate to hold the leaves from disconnection, said projection being provided with a cutaway portion to clear said retaining-lug when the door-carrying leaf is swung to fully open position.

In testimony whereof I afliX in presence of two witnesses.
